Cooling sheet

Abstract

The invention discloses a refrigeration sheet comprising a first surface having a plurality of recessed portions, a second surface opposite to the first surface, and four side faces; an inner room formed by the first surface, the second surface and the four side faces is arranged in the refrigeration sheet; the inner room is used for containing refrigeration liquid; the refrigeration liquid can be injected to the inner room of the refrigeration sheet through an injection hole; the refrigeration sheet is provided with a plurality of hollow portions respectively penetrating the first and second surfaces; the recessed portions and the hollow portions are formed on different surfaces of the refrigeration sheet so as to provide different refrigeration storage or cold releasing speeds, thereby prolonging refrigeration keeping time or delaying cold reduction speed, and cold releasing efficiency of the refrigeration sheet can be effectively applied.

Description

technical field [0001] The invention relates to a cold storage sheet, in particular to a cold storage sheet with multiple cold storage modes. Background technique [0002] At present, when goods on the market, such as general food, medicines, chemicals, etc., need to be stored at low temperature, refrigerators or freezers are mostly used to provide cooling effect with electricity. However, if there is no electricity supply at the place and time, another cold storage method without electricity can be used for low-temperature storage. This cold storage method first freezes the cold storage liquid to store cold energy, and then releases it through the cold storage liquid. Cold energy is used to provide cold insulation effect, and then achieve the effect of low temperature preservation. [0003] Most of the traditional cold storage sheets are flat rectangular shells, which can be filled with cold storage liquid to provide the cold storage effect in the cold storage container. ...

AI Technical Summary

Problems solved by technology

[0003] Most of the traditional cold storage sheets are flat rectangular shells, which can be filled with cold storage fluid to provide the cold storage effect in the cold storage container. In the case of the cold room effect of the container (for example: prolonging the cold storage time and slowing down the cooling speed), the only way to increase the number of cold storage sheets in the cold storage container is at most

As a result, the number of cold storage sheets increases, which not only increases the load of the cold storage container, but also occupies the inner space of the cold storage container, reducing the space for storing items to be kept cold in the cold storage container, causing inconvenience in use

In addition, in the case of using multiple cold storage sheets, it is more likely that the cold storage sheets are stacked on top of each other, resulting in a reduction in the surface area of ​​the cold storage sheets, making the overall cooling capacity tend to be slow or even inefficient

[0004] In addition, most traditional cold storage sheets can only provide a single cooling release mode, and cannot change the cooling release speed according to the user's needs, such as rapid cold storage, delayed cooling release
